Benefits of technology

The patent is about a system and method for converting a knee prosthesis from a cruciate retaining type to a posterior stabilizing type. This allows for a single knee implant that can be used for both types of procedures, reducing the need for revision surgeries and the associated risks and harm to patients. The technical effects of this invention include improved stability, reduced polyethylene wear, and better preservation of bone stock.

Problems solved by technology

However, there is a risk the PCL will lose function later and become deficient, which could lead to the need for revision due to instability and pain.
This type of revision is typically associated with femoral bone loss due to removal of the well-fixed femoral component, and may be particularly harmful to the patient.
